1 Claim. l

This invention relates generally to windows and is directed particularly to a'window of the type incorporating a laterally slidable sash.

In recent years the trend of modern home architecture has been away from the doublehung type window. In its place a window of shorter height mounted farther from the oor is often used. This type of window allows greater latitude in arranging furniture and is especially desirable in bedrooms and bathrooms because of the increased privacy it aiiords.

Heretofore the majority of these shorter windows have been of the pivoted-sash type, where in the sash is pivotally mounted at its lower portion to the sill of the window frame. Most of these pivoted-sash type windows are arranged so as to open outwardly. Since it is impractical to usean outside screen therewith, an inside screen is normally provided. Such inside screen. however, soon becomes coated with dirt .in most locations whereby any curtains, drapes or the like hrung adjacent the window are easily soiled. Additionally, a rather complicated and expensive sash-operating mechanism must be provided when an inside screen is used. If the sash is arranged so as to open inwardly rather than outwardly, it will interfere with any curtains, drapes or the like hung adjacent thereto at such time as it is opened.

In view of the aforementioned disadvantages inherent to the pivoted-sash type window, various forms of windows having one or more laterally slidable sashes have been suggested. Such windows, however, have heretofore failed to gain wide acceptance. The chief disadvantage of such windows has been the tendency of the movable sashes to stick within the window frame after a few months use whereby they can only be slid open or closed with considerable effort. It is a principal object of this invention to provide a window incorporating a laterally slidable sash which will remain easily movable within its frame.

It is a further object of this invention to provide a window incorporating a laterally slidable sash which will effectively restrain the entrance of water, dirt and drafts at such time as the sash is in a closed position.

It is another object of this invention to provide a window incorporating a laterally slidable sash which is easily and quietly movable within its frame. This window also provides another advantage in that it may be simply and economically constructed from standard inexpensive parts.

other objects and advantages .or the present invention will be apparent .the following detailed description of a. preferred embodiment of the. invention, .taken in conjunction with .the accompanying drawing wherein:

Figure 1 is an inside elevational view of a win-4 dew construetedin accordance with the present invention..

Figure 2 is an enlarged vertical sectional view thereoftaken online .Ile-.Ill of Figure -1,.

Figure 3 is an enlarged horizon-tal .sectional view thereof taken on line .lll-.III of Figure 2- Figure 4 is au enlarged. fragme. ary sectional view. taken on. line lit-elli 'of Figure 3.

.With particular recreme to. Figure l. a wine dowy incorporating the present invention is shown, which window comprises brcadly. Ya conventional frame, generally designated I0, wherein are mounted a central fixed sashl` and two substan tiallyidentical laterallyslidable sashes I4, one on'either side of the `central trame. m0V- able sashes L4 are each show-n in. a closed position in Figure i. They are laterally slidable within the frame I0 parallel to the longitudinal axis of the sill .23 to overlap the fixed sash. I2 so as to leave an opening of variable. size between the fixed sash andthe side element I6 of the frame.

In order that each of the laterally sldable sashes I4 will beeasily movable within the frame,

each sash i4 mounts two or more freely rotatable roller elements I1 within hollowed recesses I8 formed in the bottom portion of each such sash. These roller elements are adapted to ride upon the horizontal portion I9 of a metal guide track 20 secured to either a stool 22 aiiixed upon the sill 23, or secured directly to the sill itself, so as to support the weight of the sashes I4.

Referring to Figure 2 the movable sashes are guided in their travel at their upper ends by a top parting bead 24 and an inside stop 25 and at their bottom ends by an upstanding vertical ange 2B integrally formed upon the metal guide track 20, which flange extends upwardly within a vertical groove 28 formed within the lower portion of each sash I4.

It should Ibe noted that in addition to its function as a guide for the movable sashes I4, the upstanding flange 26 also serves as weatherstripping between the stool 22 and the bottom of the movable sashes. Hence, at such time as these sashes are in la closed posi-tion the flange 26 will -restrain the entrance of water, dirt and drafts under these sashes. With reference to Figure 3, it will be seen that when the sashes I4 are in a closed position the inner meeting rails 30 thereof and the corresponding side meeting rails 32 of the fixed sash lf2 are rabbeted, so as to restrain the entrance of water, dirt and drafts at this point. Likewise, the outer rail 34 of the movable sashes enters a weathertight recess formed by the side frame elements 1E, the side parting beads 36 and the inside stops 31.

In Figure 4 there is shown a broken-away view of a preferred means for mounting the roller elements l1 within the hollowed recesses i8 formed in the -bottom portion of the movable sashes. Each =roller element Il is shown rotatably supported upon yan axle 38 which extends between the spaced vertical side elements 40 of a metal support member, generally designated 42. This member includes a horizontal base element 44 formed integrally with the side elements 40. The side elements do not extend to the ends of the base element 44 but terminate at a point inwardly therefrom whereby are formed flat extensions 48. Each extension is bored at 50 to receive a mounting screw 52. Preferably, each recess I8 includes end portions 54 wherein the extensions 48 may be dis-posed in such a manner that at such time as the support member 42 is mounted within therecess. the lower surface thereof will be flush with the lower surface of the movable sash i4. The sup- -port member 42 is adapted to be secured to the sash by the mounting screws 52.

The roller elements 'I1 yare preferably formed of rubber whereby a minimum amount of noise will be produced when the sashes I4 are moved within the frame I0. Also, it lhas been found desirable to form the metal support members 42 and the guide track 20 of corrosion-resistant material such as brass, aluminum or stainless steel. It should be noted that the frame I and the side, top and bottom elements of the sashes are shown constructed of wood, inasmuch as it is believed that the use of this material affords the most economical and simplest construction.

It will be apparent to those skilled in this art that various other modifications may be made without departing from the spirit of the invention or the scope of the following claim.

I claim:

A window, comprising: a wooden frame in- .4 cluding a wooden sill having a generally fiat upper surface; a metal guide tra-ck secured to the upper surface of said sill having Ia horizontal portion yabutting said upper surface and a vertical portion extending upwardly from said horizontal portion; a wood-framed sash disposed above the longitudinal axis of said guide track for sliding laterally within the frame parallel to said sill, between an open position and a closed position, the bottom portion of said sash being formed with a vplurality of upwardly extending recesses open only Iat the underside of said sash, the bottom portion of said sash also being formed with a longitudinally extending vertical guide groove for -receiving the vertical portion of said guide track, whereby said vertical :portion will guide the movement of the lower portion of said sash, between said positions within said frame and said vertical portion will act as weatherstripping between said sill and the underside of said sash when the latter is in said closed position; longitudinally extending means formed upon the upper portion of said frame for guiding the movement o the upper portion of said sash within said fram-e; and, rollers mounted within said recesses for rotation upon the horizontal portion of said guide track as said sash is moved laterally within said frame.
